rustdoc: remove redundant CSS rule `#settings .setting-line`
Since the current version of settings.js always nests things below a div with ID `settings`, this rule always overrode the one above.
rustdoc: simplify JS search routine by not messing with lev distance
Since the sorting function accounts for an `index` field, there's not much reason to also be applying changes to the levenshtein distance. Instead, we can just not treat `lev` as a filter if there's already a non-sentinel value for `index`.
<details>
This change gives slightly more weight to the index and path part, as search criteria, than it used to. This changes some of the test cases, but not in any obviously-"worse" way, and, in particular, substring matches are a bigger deal than levenshtein distances (we're assuming that a typo is less likely than someone just not typing the entire name).
The biggest change is the addition of a `path_lev` field to result items. It's always zero if the search query has no parent path part and for type queries, making the check in the `sortResults` function a no-op. When it's present, it is used to implement different precedence for the parent path and the tail.
Consider the query `hashset::insert`, a test case [that already exists and can be found here](5c6a1681a9/src/test/rustdoc-js-std/path-ordering.js). We want the ordering shown in the test case:
```
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'insert' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert_with' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert_owned' },
{ 'path': 'std::collections::hash_map::HashMap', 'name': 'insert' },
```
We do not want this ordering, which is the ordering that would occur if substring position took priority over `path_lev`:
```
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'insert' },
{ 'path': 'std::collections::hash_map::HashMap', 'name': 'insert' }, // BAD
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert_with' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert_owned' },
```
We also do not want `HashSet::iter` to appear before `HashMap::insert`, which is what would happen if `path_lev` took priority over the appearance of any substring match. This is why the `sortResults` function has `path_lev` sandwiched between a `index < 0` check and a `index` comparison check:
```
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'insert' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert_with' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'get_or_insert_owned' },
{ 'path': 'std::collections::hash_set::HashSet', 'name': 'iter' }, // BAD
{ 'path': 'std::collections::hash_map::HashMap', 'name': 'insert' },
```
The old code implemented a similar feature by manipulating the `lev` member based on whether a substring match was found and averaging in the path distance (`item.lev = name_lev + path_lev / 10`), so the path lev wound up acting like a tie breaker, but it gives slightly different results for `Vec::new`, [changing the test case](https://github.com/rust-lang/rust/pull/105796/files#diff-b346e2ef72a407915f438063c8c2c04f7a621df98923d441b41c0312211a5b21) because of the slight changes to ordering priority.

Don't do pointer arithmetic on pointers to deallocated memory
vec::Splice can invalidate the slice::Iter inside vec::Drain. So we replace them with dangling pointers which, unlike ones to deallocated memory, are allowed.

Switch to `EarlyBinder` for `item_bounds` query
Part of the work to finish #105779 (also see https://github.com/rust-lang/types-team/issues/78).
Several queries `X` have a `bound_X` variant that wraps the output in `EarlyBinder`. This adds `EarlyBinder` to the return type of the `item_bounds` query and removes `bound_item_bounds`.

rustdoc: remove redundant item kind class from `.item-decl > pre`
This class originated in the very first commit of `rustdoc_ng`, and was used to add a color border around the item decl based on its kind.
4fd061c426/src/rustdoc_ng/html/static/main.css (L102-L106)
The item decl no longer has a border, and there aren't any kind-specific styles in modern rustdoc's rendering of this UI item.
Most of this PR is updating test cases so that they use `item-decl` to find the `<pre>` tag instead of relying on the fact that the class name had `rust {kind}` in it while other `<pre>` tags only had class `rust`.

Add tidy check to ensure that rustdoc GUI tests start with a small description
The first commit comes from https://github.com/rust-lang/rust/pull/106865 to prevent CI to fail.
This PR adds a tidy check to enforce having a small description at the top of the GUI test. Although the format is made to be as easy as possible to read, it's not always obvious what a test is actually checking. I think enforcing this will make it easier for us to come back on these tests if needed.

Stop probing for statx unless necessary
As is the current toy program:
fn main() -> std::io::Result<()> {
use std::fs;
let metadata = fs::metadata("foo.txt")?;
assert!(!metadata.is_dir());
Ok(())
}
... observed under strace will issue:
[snip]
statx(0, NULL, AT_STATX_SYNC_AS_STAT, STATX_ALL, NULL) = -1 EFAULT (Bad address) statx(AT_FDCWD, "foo.txt", AT_STATX_SYNC_AS_STAT, STATX_ALL, {stx_mask=STATX_ALL|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFREG|0644, stx_size=0, ...}) = 0
While statx is not necessarily always present, checking for it can be delayed to the first error condition. Said condition may very well never happen, in which case the check got avoided altogether.
Note this is still suboptimal as there still will be programs issuing it, but bulk of the problem is removed.
Tested by forbidding the syscall for the binary and observing it correctly falls back to newfstatat.
While here tidy up the commentary, in particular by denoting some problems with the current approach.

Update the wasi-libc used for the wasm32-wasi target
This commit updates the wasi-libc revision used to build with the wasm32-wasi target. This notably pulls in WebAssembly/wasi-libc#377 which is needed to fix a use case I've been working on recently. This should be a relatively small update hopefully and is not expected to have any user impact.
tidy: Don't include wasm32 in compiler dependency check
This changes the tidy compiler dependency check so that it does not include wasm32-unknown-unknown dependencies in the PERMITTED_RUSTC_DEPENDENCIES. This just helps keep the list cleaner under the assumption that the compiler will never work on wasm32-unknown-unknown.
This also fixes a bug in the check to verify there are no unused dependencies in the PERMITTED_RUSTC_DEPENDENCIES. Previously the check was verifying that the dependency was used *anywhere* in the workspace, when it should have been checking if it was used for the compiler.
There's also just a little general cleanup here. For example, the old `normal_deps_of_r` function was changed a while ago to return *all* dependencies, but the function name and description wasn't updated to remove `normal_`.
